Abstract (en)

[origin: US6000462A] In a cooling device for electrical or electronic components, in which rib-like cooling elements (3) made of good heat-conducting material are thereby connected to a base plate (2) carrying the components (1a, 1b, 1c) to be cooled that the web-like bases (3a) of the cooling elements (3) are fixed in slot-like longitudinal notches (4) of the base plate (2), the fixing is thereby improved that the groove-shaped indentation (4a) in the side wall (4c) of the longitudinal notch is shaped and dimensioned in free cross-section in such a way that the permanent molding of the side wall of the profile base (3a) takes place without essential bending deformation of the profile limbs of the cooling elements (3) rising from the longitudinal notch (4).
